Huge shout out to the Xbox One gamertags FlexPiTo, TemperingDruid2, and TeslaCommando (if the owners of those gamertags somehow stumble upon this thread)!

In case you didn't know already, the Criminal Mastermind Challenge is a challenge in Grand Theft Auto Online. It requires you to play all five heists in order, on hard, with the same group of people, all without dying. It can be quite difficult and stressful, but we beat it.
